I recently picked up a TRC-431 that had D506 and D507 removed as part of the
modulation mod. I would like to undo this so I can troubleshoot some issues
but can not find any info on what type of diodes need to be reinstalled.
The original diodes were totally cut out so I am stuck without a schematic.
Any help would be appreciated.
Thanks!

They would prob be 1N4148 diodes....but not sure..

Hi.

Go on the radio shack website. You might be able to download the manual
with the schematic. If not, give them a call and ask them. NOT the
stores, you will get blank looks.
Call the main place (tech support) , I think it's in Texas. Not sure
though.
